Abstract

Two scale-free models of elliptical galaxies are constructed using a self-consistent field approach developed by Schwarschild. Both models have concentric, oblate spheroidal, equipotential surfaces, with a logarithmic potential dependence on central distance. The axial ratio of the equipotential surfaces is 4:3, and the extent ratio of density level surfaces id 2.5:1 (corresponding to an E6 galaxy). Each model satisfies the Poisson and steady state Boltzmann equaion for time scales of order 100 galactic years.

Galaxy as fundamental calibrator of the extragalactic distance scale. I. The basic scale factors of the galaxy and two kinematic tests of the long and short distance scales

Journal Article de Vaucouleurs, G - Astrophys. J.; (United States)

A new version of the oldest approach to estimating the distances of galaxies (direct comparison with our Galaxy) is proposed to relate the extragalactic distance scale to the basic metric, photometric, and kinematic scale factors of the Galaxy. These include the galactocentric distance of the Sun, R/sub sun/, the total magnitude of the Galaxy, M/sup 0//sub T/, and its spheroidal component, M/sup 0//sub I/, the galactic rotation velocity of the local standard of rest, V(R/sub sun/), the central velocity dispersion sigma/sub ..nu../(0) of the spheroidal component, and related parameters. The following ''most probable'' values and their mean errors are adoptedmore »« less

Formation of spiral and elliptical galaxies

Journal Article Gott, III, J R ; Thuan, T X - Astrophys. J.; (United States)

The key factor distinguishing an elliptical from a spiral galaxy is proposed to be the amount of gas left over at the point of maximum collapse of the protogalaxy. The gas left depends on the ratio of the star formation time scale tau/sub s/ to the collapse time of the protogalaxy tau/sub c/. Observed properties of ellipticals imply that they formed out of relatively larger density perturbations at recombination, giving them a relatively small tau/sub s//tau/sub c/ (if a rho/sup 2/ star formation law is adopted); and thus they are expected to essentially complete their star formation by the timemore »« less

Intrinsic shape of dwarf elliptical galaxies

Journal Article Ichikawa, Shinichi - Astronomical Journal; (USA)

The intrinsic shape of the dwarf elliptical galaxies is examined. Two methods are applied to the sample of 98 dwarf elliptical galaxies in the Virgo Cluster. One is to estimate the intrinsic flattening distribution from the apparent-flattening distribution; the other is to estimate the spatial shape from the relation between the apparent flattening and surface brightness. The result of both methods are consistent with the intrinsic shape of dwarf elliptical galaxies being the oblate spheroid with a mean axial ratio of 0.6, if there is no relation between intrinsic shape and intrinsic surface brightness. It seems that dwarf elliptical galaxiesmore »« less

Dynamical models of highly flattened oblate elliptical galaxies with De Vaucouleurs' surface-brightness profiles

Journal Article Fillmore, J A ; Levison, H F - Astron. J.; (United States)

Two surveys of dynamical models of E6 elliptical galaxies were constructed with de Vaucouleurs'surface-brightness distributions. One set of models has a constant mass-to-light ratio. The other set consists of models embedded in oblate isothermal gravitational potentials. In both sets, the observed axis ratio of the models is 0.55 when viewed edge-on. When viewed edge-on, it is possible to construct models in either potential that have velocity-dispersion profiles that increase or decrease with radius along either or both principal axes. The observational data seem to indicate that dispersion profiles decrease or remain constant as function of radius. The most surprising resultmore »« less

ANGULAR MOMENTUM AND GALAXY FORMATION REVISITED: EFFECTS OF VARIABLE MASS-TO-LIGHT RATIOS

Journal Article Fall, S. Michael ; Romanowsky, Aaron J. - Astrophysical Journal Letters

We rederive the relation between the specific angular momentum j {sub *} and the mass M {sub *} of the stellar matter in galaxies of different morphological types. This is a revision of the j {sub *}-M {sub *} diagram presented in our recent comprehensive study of galactic angular momentum. In that work, we estimated j {sub *} from kinematic and photometric data that extended to large radii and M {sub *} from near-infrared luminosities L{sub K} with an assumed universal mass-to-light ratio M {sub *}/L{sub K} . However, recent stellar population models show large variations in M {sub *}/L{submore »« less
